I'm continually frustrated by suppliers who won't export parts and accessories outside their country of origin. I would have to say USA seems to be the biggest headache and to a lesser extent the UK.
I can appreciate they may have valid reasons for this, so I'm wondering if anyone knows of Freight Forwarding companies in the UK or USA that specialise in receiving goods from companies inside their country and export couriering them?

Reason is pretty simple. Fraud/theft.

It's my understanding many were tired of being ripped off. Parts are shipped after payment, but no way to certify that the parts arrived overseas at delivery address. Alleged buyer only needs to report a non receipt of the item to credit card company or paypal, then the vendor is out the money and the part.

Cant help you with courier info. Sorry.

A friend of mine does an ebay business on the side and you are exactly right. After the exact thing you described happened for the 3rd or 4th time he stopped shipping outside the US.
